WHEEL.

SPECIFICATION forming part of Letters Patent No. 381,445, dated April1'7, 1888.

Application filed September 19, 1887. Serial No. 250,122.

To to whom it may concern:

Be it known that 1, JAMES T. UPINGTON, a resident of Lexington, Fayettecounty, Kentucky, have invented certain new and useful Improvements in\Vheels, of which the following is a specification.

The several features of my invention and the advantages arising fromtheir use, conjointly or otherwise, will be apparent from the followingdescription.

In the accompanying drawings, forming part of this specification, Figure1 is a perspective View, partly sectioned, illustrating a wheelembodying my improvements. Fig. 2 is a cross-section through the centerof the hub, showing the spokes broken off.

The wheel is made in any desircd manner, and with the ends of the spokeseither straight or dovetailed.

I preferably apply my invention to wheels made with a solid hub, intowhich spokes with straight ends are driven. After the wheel is completedin the ordinary way I bore a series of holes into the hub. Each of theseholes runs practically parallel to the long axis of the hub, and eachpasses through the end of a spoke within the hub and beyond the spoke.The number of holes corresponds to the number of spokes. Into each ofthese holes I now insert a pin or screw, A, which fills the entire hole,and passing through the end of the spoke holds the same firmly inposition. \Vhile a simple pin, either of wood or metal and with- (Nomodel.)

out screw-thread, may be used for the purpose, I preferably em ployalong narrow screw, and this screw is preferably threaded only a shortdistance at the end, as shown in the drawings at a. The screw may,however, be threaded throughout its whole length. The hub is notweakened at all by the holes drilled in it, because they are entirelyfilled by the pins or screws. Indeed, the wheel is stronger than if thehub had been left intact, besides possessing the important advantage ofhaving the spokes firmly held in their sockets. The screw has theadvantage over the simple pin of being removable-a feature of importancewhen the wheel is to be repaired.

What I claim as new, and desire to secure by Letters Patent, is

I. The combination of a hub, spoke, and screw or pin, A, extendinglengthwise of the hub, transfixing the spoke, and having a screwthreadedportion engaged in the hub beyondthe spoke, substantially as and for thepurposes specified.

2. The combination of a hub, spoke, and pin extending longitudinallyfrom the end of the hub through the spoke and partially through thehubbeyond the spoke, substantially as and for the purposes specified.
